Product details
Overview
F280033SPM from Texas Instruments is a C28x-based real-time microcontroller designed for high-efficiency power electronics control, featuring a 120-MHz 32-bit DSP core with IEEE 754 FPU, 128KB ECC-protected flash, 69KB ECC-protected RAM, and integrated analog peripherals including three 4-MSPS 12-bit ADCs and 16 ePWM channels with 8 high-resolution (150-ps) outputs. It targets motor drives, digital power converters, and EV charging systems.
For engineers reviewing the F280033SPM datasheet, F280033SPM pinout, F280033SPM application, or F280033SPM equivalent, this page delivers verified technical context, package-specific pin functions, functional safety support (ASIL B/SIL 2), CLB-augmented peripheral flexibility, and precise alternative selection guidance for industrial and automotive power control designs.
Technical Context
The F280033SPM implements a deterministic real-time control architecture centered on the C28x CPU running at 120 MHz with hardware-accelerated math units (FPU, TMU, VCRC) and dedicated diagnostics (ERAD, HWBIST, MPOST). Its control subsystem integrates 16 ePWM channels - eight supporting 150-ps resolution - with hardware trip zones, dead-band generation, and synchronized ADC triggering.
Analog signal acquisition is tightly coupled via three independent 4-MSPS 12-bit ADCs, each with four post-processing blocks (PPB), alongside four windowed comparators (CMPSS) with 12-bit reference DACs and two buffered 12-bit DAC outputs. The device supports CAN FD, FSI (200 Mbps), and dual I²C for robust system-level communication in noisy power environments.

Equivalent & Alternatives
The following parts are listed as comparable options for similar real-time control applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TMS320F280034 | Same 128KB flash, 69KB RAM, and PM package; includes CLA (Control Law Accelerator) and 4 CLB tiles - adds parallel floating-point math acceleration and enhanced logic programmability. | Supports more complex control algorithms (e.g., predictive current control, multi-variable NLPID) requiring CLA offload; suitable where CPU headroom is constrained. | Select F280034 when CLA-based task partitioning or CLB-based custom encoder interfaces are required; F280033SPM remains optimal for cost-sensitive, CLA-free implementations. |
| TMS320F280037C | 256KB flash (vs. 128KB), same 69KB RAM, CLA, 4 CLB tiles, and PZ/PN/PM package options - doubles program storage for larger control stacks and safety-certified code partitions. | Required for ASIL B-certified designs needing redundant firmware images, bootloader + application separation, or extended diagnostic routines per ISO 26262. | Choose F280037C for functional safety deployments demanding larger flash for dual-image firmware or certified runtime diagnostics; F280033SPM fits non-safety-critical, compact-control applications. |
Compared with TMS320F280034 and TMS320F280037C, the F280033SPM offers identical analog/peripheral integration and timing precision but omits CLA and uses half the flash capacity - making it ideal for cost-optimized, single-image motor control and digital power applications where algorithm complexity and safety certification are not required.

FAQ
What is the maximum operating junction temperature for the F280033SPM?
The F280033SPM has a specified junction temperature range of –40°C to 150°C. This rating applies to all package variants including the 64-pin PM LQFP, enabling reliable operation in high-thermal-load environments such as enclosed motor drives and power supply enclosures. Thermal derating guidelines per TI's SPRSP61C datasheet must be followed for sustained 150°C operation.
Does the F280033SPM include a Control Law Accelerator (CLA)?
No, the F280033SPM does not include a Control Law Accelerator (CLA). According to TI's official device comparison table (SPRSP61C), CLA is omitted in the F280033 and F280033-Q1 variants, distinguishing them from higher-tier F280034/F280037 devices. All real-time control tasks execute solely on the 120-MHz C28x CPU with FPU, TMU, and VCRC support.
Which communication interfaces does the F280033SPM support for automotive applications?
The F280033SPM supports CAN FD (MCAN) and LIN interfaces compliant with automotive protocols, along with two I²C ports and two SCI/UART modules usable for diagnostic and configuration links. While the F280033SPM itself is not AEC-Q100 qualified, its pin-compatible F280033-Q1 variant meets AEC-Q100 Grade 1 (–40°C to 125°C TA) and supports ASIL B functional safety requirements.
How many ADC channels are accessible on the F280033SPM in the 64-pin PM package?
In the 64-pin PM package, the F280033SPM provides 16 external single-ended ADC input channels, as confirmed in TI's Device Comparison table. These include dedicated ADCIN pins plus analog-capable GPIO (AGPIO) pins, supporting full utilization of all three 4-MSPS 12-bit ADC modules with synchronized sampling and post-processing block (PPB) support.
Is the F280033SPM compatible with C2000™ real-time control development tools?
Yes, the F280033SPM is fully supported by TI's C2000™ ecosystem, including C2000Ware software libraries, ControlSuite, Code Generation Tools v22.x+, and CCS IDE v12.x+. It is also compatible with the TMDSCNCD280039C evaluation board via pin-mapped headers, enabling rapid prototyping of motor control and digital power applications using out-of-box examples and HAL drivers.
